Description

Technical Field

[0001] The utility model relates to the technical field of isostatic graphite processing, in particular to an isostatic graphite lifting device. Background Art

[0002] Isostatic graphite is a specialty graphite material characterized by high purity, fine grains, uniform density, and low porosity. Its primary benefits include outstanding wear resistance, corrosion resistance, high-temperature tolerance, and excellent thermal and electrical conductivity. These properties have made isostatic graphite an essential material in a wide variety of fields, making it an indispensable material in modern industry.

[0003] During the calcination process, the binder and coal tar pitch within the cold isostatically pressed blank decompose into gases that escape. Consequently, numerous pores of varying sizes form within the calcined product. The presence of such a large number of pores negatively impacts the performance of the calcined product, for example, reducing its density, increasing its resistivity, and decreasing its mechanical strength. To compensate for these internal defects caused by the calcination process, the calcined product must be impregnated with a suitable impregnant to effectively fill these pores and cracks.

[0004] During the impregnation process, a crane connected to a sling is required to lift the product into the impregnation tank to achieve the lifting and transportation of the graphite blank.

[0005] Based on this, the utility model proposes a lifting device which effectively avoids technical problems such as tilting, dumping and collision of graphite blanks during lifting, so as to ensure the lifting stability of the graphite blanks. Utility Model Content

[0006] The purpose of the utility model is to provide an isostatic graphite lifting device, which can effectively maintain the stability of the graphite blank during the lifting process, thereby effectively avoiding technical problems such as tilting, dumping and collision of the graphite blank due to unstable lifting.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

DETAILED DESCRIPTION

[0023] Example 1

[0024] An isostatic graphite lifting device, such as Figure 1-3 As shown, it includes a support frame 1, a top plate 2 arranged on the support frame 1, a movable plate 3 arranged below the top plate 2 and capable of displacement along the length direction of the top plate 2, two vertical telescopic components arranged below the movable plate 3 and capable of moving in a direction perpendicular to the moving direction of the movable plate 3, a hanging part 4 fixedly arranged below each of the vertical telescopic components, and a lifting box 5 detachably arranged on the two hanging parts 4; the side walls and bottom walls of the lifting box 5 are provided with a plurality of holes (existing technology, not shown in the figure) to facilitate the penetration of the impregnation liquid through the lifting box 5; the top wall of the lifting box 5 is provided with a hanging ear 6 adapted to the hanging part 4. Further, as Figure 1-3 As shown, the bottom end of the top plate 2 is provided with an electric slide rail 7, and the top end of the movable plate 3 is provided with a slider 8 adapted to the electric slide rail 7. Figure 1-4As shown, two vertical plates 9 are provided below the movable plate 3, and a slide rod 10 and a screw rod 11 are provided in parallel between the two vertical plates 9. One end of the screw rod 11 is connected to a motor 12 provided on one of the vertical plates 9; the two ends of the screw rod 11 are respectively connected to the two vertical plates 9 for rotation; the two ends of the slide rod 10 are respectively fixedly connected to the two vertical plates 9. In addition, as Figure 3 and Figure 4 As shown, the screw rod 11 is divided by the vertical plane where the midpoint is located, and is provided with two sections of thread teeth with opposite thread directions, so that the two vertical telescopic components can move synchronously towards or away from each other. The two vertical telescopic components are respectively sleeved on the outside of the slide rod 10 and the screw rod 11; the vertical telescopic component and the slide rod 10 are slidably connected, and the vertical telescopic component and the screw rod 11 are threadedly connected. Further, as Figure 1-4 As shown, the vertical telescopic assembly includes a connecting plate 13 sleeved on the screw rod 11 and the slide rod 10, a first hydraulic rod 14 arranged below the connecting plate 13, and a connecting block 15 arranged at the bottom end of the first hydraulic rod 14; the hanging part 4 is arranged at the bottom end of the connecting block 15, as shown in FIG. Figure 3 As shown, the hanging portion 4 is a horizontal plate.

[0025] Working principle: Place the lifting box 5 just below the moving plate 3, and place the graphite blank in the lifting box 5, then start the two first hydraulic rods 14 to move the horizontal plate down to be flush with the hanging ear 6, then start the motor 12, under the action of the motor 12, the vertical telescopic components move toward each other until the two horizontal plates extend into the hanging ear 6, turn off the motor 12, and then retract the first hydraulic rod 14, so that the lifting box 5 can be moved upward, then start the electric slide rail 7. Move the lifting box 5 along the length of the horizontal slide rail. Since the immersion tank (not shown) is located directly below one end (i.e., the left end) of the horizontal slide rail, when the lifting box 5 moves directly above the immersion tank, activate the first hydraulic rod 14 to move the lifting box 5 downward until it contacts the bottom of the immersion tank. Then, activate the motor 12 to move the two vertical telescopic components in opposite directions, thereby separating the horizontal plate and the hanging lug 6. Then, retract the vertical telescopic device to move the horizontal plate upward. At this point, the immersion operation can be carried out.

[0026] Example 2

[0027] Because the hanging ears 6 in Example 1 are not limited when they are hung on the horizontal plate, when under external force, it may cause the lifting box 5 to shake. Based on this, on the basis of Example 1, as shown in FIG. Figure 5As shown, a second hydraulic rod 16 is provided on each side of the two connecting blocks 15 that are close to each other, and a pressure plate 17 is provided at the bottom end of the second hydraulic rod 16. In this solution, after the hanging lug 6 is hung on the horizontal plate, the second hydraulic rod 16 is activated to move the pressure plate 17 downward until it abuts against the hanging lug 6. In this way, the hanging lug 6 is firmly fixed between the horizontal plate and the pressure plate 17, further improving the lifting stability of the lifting box 5.

[0028] Further, such as Figure 1-2 As shown, based on Example 1 or Example 2, the bottom wall of the lifting box 5 is provided with support legs 18. By providing the support legs 18, a certain gap is left between the bottom wall of the lifting box 5 and the bottom wall of the immersion tank, so that the immersion liquid can enter the lifting box 5 through the holes provided in the bottom wall of the lifting box 5.

[0029] Further, such as Figure 1-2 As shown, a placement plate 19 is provided at the bottom end of the support frame 1, and the placement plate 19 is disposed directly below the two hanging portions 4. The placement plate 19 is provided with the same number of placement holes (not shown) as the number of the support legs 18. In this solution, the placement holes facilitate the placement of the support legs 18 therein, thereby limiting the position of the lifting box 5 and ensuring that the lifting box 5 can be placed directly below the movable plate 3 before lifting.
